Okay, this is a big one. Some changes are experimental, excited to see your feedback so I can tweak everything to perfection!

FEATURES

New feature: Difficulties!

• After surviving the normal difficulty, you can now progress Nightmare 1 to 5
• Every hero has his own difficulty progression
• The nightmare modifiers will add unique challenges to the game

New feature: Items!

• Every boss will now drop a chest containing an item (plus additional loot)
• Items are a good opportunity to get mighty upgrades, but they have cursed modifiers that might alter your gameplay

Damage type rework!
The damage types and modifiers caused confusion, so I streamlined them:

• Physical Damage: 75% chance to knock back enemies on hit on default
• Fire Damage: 50% chance to burn enemies on hit on default
• Ice Damage: 30% chance to freeze enemies on hit on default. Frozen enemies take additional frost damage on hit
• Arcane Damage: +1 projectile chain on default. Projectiles deal 50% more damage after every chain

The following perks will unlock perks that are specialized on these damage types:

• Manual Of Might
• Scroll Of Fire
• Book Of Ice
• Tome Of Mysteries

I tweaked alot of perks to fit the rework and added a bunch of new ones.

• New modifier: Knockback on hit
• You can now toggle auto attack with the right mouse button
• You can now see an overview of active perks and items when you pause the game or get a new perk/item
• Added a spawn animation to drops
• Added a sound effect to xp pickups
• Added categories to the achievement panel
• Added a bunch of new achievements, the total is 52 now

(Since I rearranged some achievements, I changed how the heroes get unlocked. You might have to unlock them again.)

TWEAKS

Aric changes:

• Aric got two perks: Get a full heal every time you kill a boss & Knock back close enemies when you crit
• Slightly increased the attack speed of Aric but reduced his range

Ember changes:

• Reworked his perks due to the damage type rework. He is now able to spread burns instead
